Hi @bellis-ai, thanks for filing this. I can replicate it so I've marked as confirmed.

This is a problem in our upstream type library go-cty. It seems we've previously fixed this for lists and sets, but maps were missed as the original reproduction didn't cause this problem in maps. This reproduction exposes the issue in maps, so we can roll out a fix for it.

You can follow the potential fix to the library here: zclconf/go-cty#198.

The fix has been merged upstream, we're waiting for the next version of the library to be released.
